Fields and buttons have a 'visible' attribute. what you can do is bring up
the message box and type:

	set the visible of background field "field Name" to false

And it'll go away. VERY convenient. 

I also have a script I put in my home stack that will walk through
all of the cards and backgrounds of a stack and make everything visible
again -- it turns out that once you make something invisible, it is almost
impossible to find again. I'll have to upload it in the next couple of days.
